Peeling apparatus for positive electrode current collector and positive electrode composite

Abstract

Provided is a peeling apparatus for a positive electrode current collector and a positive electrode composite, the peeling apparatus including: a current-carrying area including an electrode; a shock wave delivery area configured to house a positive electrode plate; a partition plate configured to partition between both the areas; and a power supply device configured to supply electric power to the electrode, the peeling apparatus being configured to peel off the positive electrode composite from the positive electrode current collector of the positive electrode plate in such a manner that a discharge occurs between the electrode and the partition plate and a shock wave generated in the current-carrying area is delivered through the partition plate to the positive electrode plate in the shock wave delivery area.
